DEVI-CE'. FOR CONVERTING MOTION.

SPECIFICATION forming part Ilof Letters Patent No. 279,651, dated June19, 1883.

Application filed February 17, 1883. (No model.)

.To all whom it may concern Beit known that I, WARREN T. KnLLoGG, ofOohoes, in the county of Albany and State of New York, have inventedcertain new and useful Improvements in Devices for ConvertingReciprocating into Rotatory Motion, of which the following is aspecification.

My invention relates to that class of devices whereby an intermittentreciprocating 'or vibratory motion is converted into a continuousrotatory one; and the obj ect of my invention is to provide a simple,cheap, and reliable device for the purpose above set forth. This objectI attain by means of the mechanism illustrated in the accompanying`drawings, which form part of this specification, and in which- Figure lis a side elevation of my improved device as applied t0 a cog-wheel;Fig. 2, avertical section of same at the line X X; and Fig. 3, anenlarged rear view of the vibratile pawlholder, showing theratchet-wheel in section.

As represented in the drawings, A is the driving-wheel, which may bemade either with or without cogs or teeth around its perimeter. Saiddriving-wheel is provided with a ratchetwheel, B, which may bemadeeither integral with or of a separate piece from said drivingwheel.The driving-wheel A may be adapted to revolve on a iiXed stud, G, asshown in the drawings; or, when preferred, it may be secured to arevolving shaft, so as to rotate therewith.

The pawl-holder consists of a vibratile segment, D, that is fitted tovibrate freely on, but independently of, the stud or shaft C. Saidpawl-holder is provided with a series of recesses, d, which are formedin the segmental flange d', and each recess contains a pawl, E, that isadapted to vibrate on a free or imaginary center in the smaller end dlof its recess; and for the purpose of facilitating and simplifying theconstruction of the device, all of said pawls are made of a uniform sizeand form. The recesses d are arranged Ato divide the pitch7 of the teethonthe ratchet-wheel B in such manner that the engaging points of thepawls E will vary in respect to the points of the ratchet-teeth, and sothat some one of said pawls will be sure to engage with a ratchet-toothat any point of the vibratory movement of the segment D, and by thismeans a positive engagement of one of the pawls with one of theratchet-teeth is effected with but little, 4if any, lost motion of thesegment. Vhen the several parts ofthe device are in position, the pawlsE are retained in the recesses d by means of the circular plate a',formed in the centerof the wheel A. The segment D is provided on itsouter face with lugs d, to whiclr an operating lever or brake, F, ispivoted, (by means of a bolt, f,) so as to have a slight lateral motionto enable it to yield to any sway of the body of the operator. Abearing-lug, d, is also formed on the outer face of the segment D, tosupp ort the brake F and' relieve the lugs d from any excessive strainthat might otherwise be thrown upon them by said brake. rIhe segment Dis retained in position 011 the shaft C by means of an adjustablecollar, c.

As represented in the drawings, the device is provided with a series ofsix of the vibrating pawls E; but I do not limit myself to that precisenumber, for it is obvious that as long as said pawls can be arrangedaround the periphery of the ratchet-wh eel in positions where the forceof gravity can be utilized for vibrating the free ends of them intoengagement with the radial faces of the ratchet-teeth, any

other nulnber, either greater o1' lesser, may be employed 5 but itshould be borne in mind that with a large number of the pawls the pitchof the teeth of the ratchet-wheel can be more minutely divided, andthereby a slighter lost motion of the vibratile segment D can beobtained.
